repo2docker fetches a repository (from GitHub, GitLab, Zenodo, Figshare, Dataverse installations, a Git repository or a local directory) and builds a container image in which the code can be executed. The image build process is based on the configuration files found in the repository. repo2docker can be used to explore a repository locally by building and executing the constructed image of the repository, or as a means of building images that are pushed to a Docker registry.

jupyter_kernel_test is a tool for testing Jupyter kernels. It tests kernels for successful code execution and conformance with the Jupyter Messaging Protocol.

ipywidgets, also known as jupyter-widgets or simply widgets, are interactive HTML widgets for Jupyter notebooks and the IPython kernel.

This package provides a hatch plugin to help build Jupyter packages.

This package provides a set of widgets to help facilitate reuse of large datasets across widgets.

GNU Kawa is an implementation of the Scheme programming language that is built on top of the Java platform. It is thus conveniently integrated with Java and benefits from this by having a compiler, optional static typing, and so on. Kawa also serves as a framework for implementing other programming languages on the Java platform. Included in Kawa is qexo, a partial implementation of XQuery in Java.

This package provides a QtQuick plugin to render beautiful and interactive charts.

Analitza is a library to work with mathematical objects. It adds mathematical features to your program, such as symbolic computations and some numerical methods; for instance the library can parse mathematical expressions and let you evaluate and draw them.

KAlgebra is a calculator that lets you plot different types of 2D and 3D functions and to calculate easy (and not so easy) calculations, such as addition, trigonometric functions or derivatives.

Marble is similar to a desktop globe. At closer scale it becomes a world atlas, while OpenStreetMap takes the user to street level. It supports searching for places of interest, viewing Wikipedia articles, creating routes by drag and drop and more.

Gcompris offers a large collection of educational games for small children, designed to be a unified interface to integrate more educational games. Language-oriented games contain vocabulary, sounds, and voices for many different languages. Currently available boards include:

1. learning how to use a mouse and keyboard

2. learning simple arithmetic

3. learning how to read an analog clock

4. recognize letters after hearing their names

5. reading practice

6. small games (memory games, jigsaw puzzles, ...)

LabPlot is a tool for interactive graphing and analysis of scientific data. It provides an easy way to create, manage and edit plots and to perform data analysis.

KTouch is an aid for learning how to type with speed and accuracy. It provides a sample text to type and indicates which fingers should be used for each key. A collection of lessons are included for a wide range of different languages and keyboard layouts, and typing statistics are used to dynamically adjust the level of difficulty.

This framework contains scripts and data for building API documentation (dox) in a standard format and style for KDE.

For the actual documentation extraction and formatting the Doxygen tool is used, but this framework provides a wrapper script to make generating the documentation more convenient (including reading settings from the target framework or other module) and a standard template for the generated documentation.

KCrash provides support for intercepting and handling application crashes.

KNotification is used to notify the user of an event. It covers feedback and persistent events.

Framework Integration is a set of plugins responsible for better integration of Qt applications when running on a KDE Plasma workspace.

KConfig provides an advanced configuration system. It is made of two parts: KConfigCore and KConfigGui.

KConfigCore provides access to the configuration files themselves. It features:

1. Code generation: describe your configuration in an XML file, and use `kconfig_compiler to generate classes that read and write configuration entries.

2. Cascading configuration files (global settings overridden by local settings).

3. Optional shell expansion support (see docs/options.md).

4. The ability to lock down configuration options (see docs/options.md).

KConfigGui provides a way to hook widgets to the configuration so that they are automatically initialized from the configuration and automatically propagate their changes to their respective configuration files.

KDED stands for KDE Daemon. KDED runs in the background and performs a number of small tasks. Some of these tasks are built in, others are started on demand.

The KNewStuff library implements collaborative data sharing for applications. It uses libattica to support the Open Collaboration Services specification.

KDESU provides functionality for building GUI front ends for (password asking) console mode programs. kdesu and kdessh use it to interface with su and ssh respectively.

KPeople offers unified access to our contacts from different sources, grouping them by person while still exposing all the data. KPeople also provides facilities to integrate the data provided in user interfaces by providing QML and Qt Widgets components. The sources are plugin-based, allowing to easily extend the contacts collection.

This is a DAV protocol implementation with KJobs. Calendars and todos are supported, using either GroupDAV or CalDAV, and contacts are supported using GroupDAV or CardDAV.
